v1.14.0

Minor Changes

• #518 516725f Thanks @sameelarif! - act() can now use observe() under the hood, resulting in significant performance improvements. To opt-in to this change, set slowDomBasedAct: false in ActOptions.

• #483 8c9445f Thanks @seanmcguire12! - When using textExtract, you can now do targetted extraction by passing an xpath string into extract via the selector parameter. This limits the dom processing step to a target element, reducing tokens and increasing speed. For example:

  const weatherData = await stagehand.page.extract({
    instruction: "extract the weather data for Sun, Feb 23 at 11PM",
    schema: z.object({
      temperature: z.string(),
      weather_description: z.string(),
      wind: z.string(),
      humidity: z.string(),
      barometer: z.string(),
      visibility: z.string(),
    }),
    modelName,
    useTextExtract,
    selector: xpath, // xpath of the element to extract from
  });

• #556 499a72d Thanks @kamath! - You can now set a timeout for dom-based stagehand act! Do this in act with timeoutMs as a parameter, or set a global param to actTimeoutMs in Stagehand config.

• #544 55c9673 Thanks @seanmcguire12! - you can now deterministically get the full text representation of a webpage by calling extract() (with no arguments)

• #538 d898d5b Thanks @sameelarif! - Added gpt-4.5-preview and claude-3-7-sonnet-latest as supported models.

• #523 44cf7cc Thanks @kwt00! You can now natively run Cerebras LLMs! cerebras-llama-3.3-70b and cerebras-llama-3.1-8b are now supported models as long as CEREBRAS_API_KEY is set in your environment.

• #542 cf7fe66 Thanks @sankalpgunturi! You can now natively run Groq LLMs! groq-llama-3.3-70b-versatile and groq-llama-3.3-70b-specdec are now supported models as long as GROQ_API_KEY is set in your environment.
